Just wanted to emphasize, as someone else has already posted (and I omitted in my post) - your mages/SPs/locks need to dance in and out of the field a bit if they go low enough on health to need healing and cannot afford a block or can't get a BoP...

Dunno if this will be of any use, but here's our first kill a while back from a disc Priest (my offspecc so excuse my randomness at times) and resto Shaman PoV. We only Bop'ed the person with the Cry of Terror, rest of group 4 (the soakers) got shields and SS spammed, and as mentioned in the above post they sometimes had to jump in and out of Fields to get healed. After we focused SS on them as Sha spawned they seemed to be fairly ok though.

We ended up having a lot of people out for valentines day and had to makeshift our healing comp with more OS healers. But we got it to work.

Our comp was
Disc x3
Druid x2
shaman
paladin
Monk

Having only one mana tide totem sucked a lot and having our 2 new shadow priest apps play disc was kind of iffy at first but they pulled through for us. We ended up using 2 mages that went in every single corrupted. With two warlocks and a 3rd mage go in some of the corrupted to burn them more quickly. P3 was easy but we had someone blow up in the raid at the end, but we still killed it. I'm very pleased ^_^

At first we were getting so scared of p3 but its really not that intense ^^ gz for the kill, x3 disc definitely should've helped for that fight so I wouldn't feel iffy about it.
